Monocolor Radiation Source Based on Low-Energy Electron Beam and DcFields With High Gradient of Electromagnetic Energy Density

摘要

An ideal radiation source is required to be of desirable frequency spectrum (for example, the most desirable is monocolor) and high total output power. Pursuing a high total power often drive people to consider a technique route based on electron beam [1-12]. Many routes of radiation generation [1-12] hire the electron beam in different ways. For example, in free electron laser (FEL) [1,2], an electron beam interacts with a combined field of magnetic components and incident electromagnetic (EM) wave to generate radiations at new frequency components differing from the incident wave. Bremsstrahlung refers to the interaction of such a beam with 3-D ionic Coulomb potential and usually has a broad frequency spectrum [13].
